Why This Exists

AI plugins today have a trust problem. Most are demos — not production tools. They hardcode credentials, skip confirmation on destructive actions, and have no concept of agent boundaries.

We built SOSA™ (Supervised Orchestrated Secured Agents) to fix that — a four-pillar methodology for production-grade autonomous AI operations. Every plugin in this marketplace declares its compliance level, impact classification, and security posture.

The four pillars:

Pillar	In Practice
🛡️ Supervised	High-impact actions require human approval. An outreach agent can't send 500 emails without your sign-off.
⚙️ Orchestrated	Agents follow Plan → Act → Verify. Token budgets are enforced — bloated skills waste your money.
🔒 Secured	No hardcoded credentials. External data is scanned for prompt injection. Package versions pinned.
🤖 Agents	Each agent has a formal role spec, declared tool access, and explicit boundaries. A finance agent can't send emails — period.
